INTERNET challenges are not a new trend – but this challenge might just leave you questioning what the world is coming to.

In the last few years we have seen people eat spoonfuls of cinnamon, throw buckets of ice water over their head, use shot glasses to ‘puff up’ their lips in the Kylie Jenner lip challenge, dance the running man and, most recently, remain completely still for the mannequin challenge.

The newest challenge trending on Twitter is the #greysweatpantschallenge, and vain men are loving it.

The ‘challenge’ is for men to put on grey jogging bottoms and take a photo, because the light colour and fabric tends to enhance their manhood well.

So, if you’re a well-endowed man, then the sweatpants do you a favour.

But this not-so-challenging ‘challenge’ has backfired hilariously and these arrogant men are being mocked by others, hard.
